Re: ZR1 brake lines
 

Hello.

Genuine GM brake caliper hoses for ZR1 are the following:

FRONT: P/N 10222295 2 required L or R
REAR : P/N 10222294 2 required L or R

Alternatively, you can purchase ACDelco hoses with this part numbers:

FRONT: GM P/N 18032754 - ACD P/N 18J1043 L or R
REAR : GM P/N 18032753 - ACD P/N 18J1042 L or R

Regular C4 brake hoses are different GM part numbers, depending on the Model Year vehicle and if you have heavy duty brakes RPO.

With vehicle VIN number I can send to you exact GM part numbers for your car.

Thanks.

Ramon




And remember....


ZR1 means PUSHROD FREE.

GBRTNG,

Comparing the 11" wheels vs. 9.5" wheels on the rear of the car the tire would stick out 20mm on the outside and 18mm on the inside (based on 36mm and 56mm offset).

So not all of the width is on the outside under these conditions. That will explain the slightly longer brake line on the Z. If the line is properly turned the standard C4 length line should clear on the ZR1. Would it clear a 335 tire? I wonder.

I'll make some measurements the next time I have the car on a llft.
